I'm not sure if there's any new info, but Disney did put up a Halloweentime "Event" on Facebook:

I didn't remember them saying the characters would "parade" down Main Street but that's not a huge priority for me so I don't know....
It's basically the characters strolling down the street for 5 - 10 minutes to kind of show everyone who is there, I think, just like they did at the TOTP in DCA (which happened so quickly at the TOTP in 2008 that my friend and I totally missed it). In other words, it's not something to really plan a chunk of time around.
I have a feeling by the time the 17th rolls around, we will almost be in need of a new thread so we have room for everyone's pictures! Isn't the page limit 200? If so, we only have 45 more pages to go!
I'll be there the 15th-19th, and will be sure to take lots of photos.
Woo hoo! That's right - you'll be one of the 'opening day' people!! I wonder how much stuff will be up on, say, the 15th when you arrive as opposed to the 17th, when the season officially begins. We know the goodies will already be on sale, but will they wait until the wee hours between the 16th and 17th to roll out the giant Mickey pumpkin?
